大家可以看到，大部分时间被"log4j:WARN No appenders could be found for logger (org.springframework.web.context.ContextLoader).
log4j:WARN Please initialize the log4j system properly."花费掉了。

我在网上搜这个信息，试了很多方法都不行。包括拷贝log4j.properties到classes目录下，还是提示这个问题，仍然启动慢。以下是lib信息:

这个是告诉你，你没有配置log4j的日志.并请你初始化log4j的系统属性.

log4j是用来记录日志的.

系统启动的时候.把启动记录记下来.

你这里没有配.它应该是不会是主要耗时因素吧？

你机子什么配置?我890M内存.AMD3400+cpu， tomcat上部署的系统有5个模块，启动速度是50秒左右. 我觉得你的这个启动信息来看，应该是正常的..

请下面高手指正.

[李发展]

我的是笔记本，1G内存，奔腾M1.6的。
请问具体怎么初始化log4j的系统属性。

顺便说声，我考虑开发阶段经常重启tomcat，我打算去掉log4j,我用的是ssh2的框架。
把log4j.jar去掉后，原以为不会出现“log4j:WARN No appenders could be found for logger (org.springframework.web.context.ContextLoader).
log4j:WARN Please initialize the log4j system properly”这个提示，结果还是出现了。奇怪。

[李发展]

删除log4j.jar现在是可以了，不会出现该问题。

如果保留log4j.jar的话，还是老样子。哪个高手可以解答下？谢谢。

如果只是把一个log4j.properties放到classes下，并在web.xml上加个配置，好像不起作用。

[WuBill]

再加1G内存，估计就不会有这烦恼了*_*

[gpogpo]

我也有这个问题,请高手指点一下吧

你可以调试一下log4j的输出等级
如果你在server.xml中配置了多个服务的话,你可以在别的服务不用的时候注掉.
<Context ....
..
</Context >
还有一种可能就是spring的beans
默认default-lazy-init为false，导致在启动时候，会默认加载整个对象实例图，导致速度慢 ， 把beans的default-lazy-init改为true的话，spring在启动的时候并没有真正实例化对象，而只是用一个代理来实现。当真正需要调用该类的时候，才会去实例化

[leopoincare]

真的跟当掉了一样

[zf694142242]

我的文件中没有log4j文件不知到动了哪里 就出来这个
信息: Initializing Spring root WebApplicationContext
log4j:WARN No appenders could be found for logger (org.springframework.web.context.ContextLoader).
log4j:WARN Please initialize the log4j system properly.
就是启动时到这里挺费时的撒 可不可以在启动时后不加载log4j:WARN 可以不咋配置撒 谢了

[ttsoft888]

我的在myEclipse里启动需要6分钟，在tomcat安装目录下启动，不到1分钟，不知道为什么？
